CUR-NER-PQST FASTENING.

Specification of Letters Patent.

Patented Dec. 8,191

Application filed June 14-, 1913. Serial No. 773,578.

To all whom it may concern Be it known that I, AARON WOLF, a citi zen of the United States, and resident of New York city, in the county of New York and State of New York, have invented certain new and useful improvements in Corher-Post Fastenings, of which the following is a specification.

This invention relates to certain improvements in corner post fastenings, for bedsteads, and more particularly to the general type shown in the prior Patent No. 1,048,256, issued December 24th, 1912, to myself and Antoni Governale, and in the prior co-pendi-ng application, Serial No. 7 03,004, filed June 11th, 1912, by us. i The main objects of my present invention are to provide an improved lug formation for more effectively holding the cross rail to improve and simplify the connection between the side rail and the corner post and to provide an improved connection between the fastening member and the corner post to prevent wear or injury of the latter, to conceal the opening in the former. and to remove the necessity for absolute accuracy in manufacture.

In my present construction I also provide an improved construction facilitating the insertion of the retaining wedge and provide a simple and efficient means for connecting the foot and head members when the bedstead is on exhibition and the normal side rails removed.

My invention involves other features which together with the details pf the features above referred to will be more ar ticularly pointed out hereinafter and de ned in the claims.

Reference is had to the accompanying drawings in which similar characters of reference indicate corresponding parts throughout the several views, and in which- Figure 1 is a top plan view of a construction embodying one form of my invention, the corner post, base plate and wedge being shown in section; Fig. 2 is. a perspective view of the tubular member of the corner post fastening; Fig. 3 is a perspective view of the terminal portion of the side rail; Fig.

at vis a perspective view of the base plate; Fig. 5 1s a perspective view of the wedge for use within the corner pest; Fig. 6 is a perspective view of a substitute side rail used for exhibition purposes; and Fig. 7 is a top planview of portions of the head and foot of the bedstead connected by the substitute side rail shown -in Fig. 6.

referred to and adapted to be secured to a hollow metal post 11. The tubular member is formed from a sheet metal blank bent to bring opposite edges together and to form four sides including the top 12, the bottom 13 and the two vertical side walls 14: and 15. The top and bottom walls have extensions 16 adapted to enter transverse slots in the post 11 and each extension is provided with a perforation or aperture 17 for the admission of a wedge 18 movable lengthwise of the post within the latter. The wcdgc is preferably formed of a piece of sheet metal bent to substantially semi-cylindrical or V- shape and tapered toward one end. The metal is so drawn that at the smaller end there is an end wall 19 inclined in respect to the general direction of the length of the pin so that the pin terminates in an edge in the plane of the longitudinal side edges, which greatly facilitates the admission of the pin or wedge to the apertures 17 and facilitates the drawing of the tubular member 10 into proper and rigid engagement with the post. This pin by being formed in this manner is less expensive than the cast metal pin shown in the prior patent above referred to and as it is hollow the opposite side edges have resiliency permitting the roper engagement with the sides of the iiole. This insures the fit of the pin or wedge without the absolute accuracy otherwise required.

One of .the special features of my present invention involves an improved construction facilitating the rigid attachment of the cross brace of-the head or foot frame of the bedstead. The meeting edges of the blank may be at either the upper or lower corner of the member and either at the inner or at the outer side, but is preferably at the upper inner corner as shown particularly in Fig. 2. The top wall 12 and the side wall 15 meet at the upper inner corner of the member with the top wall projecting out over the side wall. The top wall is provided with apertures and the side wall has lugs 20 adapted 'to extend through these apertures and to be riveted over to secure the edges permanently together. Extending downwardly from the upper edge of the side wall 15 is an L-shaped slot defining a portion of the side wall which may be bent outwardly at right angles to the plane of the side wall, and constitute a lug'2l. The top wall has an extension 22 lying in its own plane and extending out from the lug 21, so that the upper edge of the latter acts as a support for the outer free end of the former and the parts 21 and 22 lie in planes at right angles to each other and their meeting edges are at right angles to the general direction of the length of the tubularmember 10. These lugs or flanges are of such size and so positioned that across brace'23 may be rigidly secured to each of them by bolts,

rivets or other suitable means. The cross brace is ordinarily 1n the form of an angleiron and as the two flanges 21 and 22 are in planes at right angles to each other, the angle-iron may be rigidly secured to both flanges and thus prevented from tilting or swinging as might occur if only one flange were employe Furthermore, the cross brace can not be displaced by the bending of either one of the two lugs or flanges.

In the specific construction illustrated in the prior Patent No. 1,048,256,the side rail is in the form of an angle iron abutting against the end of the tubular member and the side rail carries a tubular member adapted to extend into the tubular member carried by the corner post. In the specific form illustrated in the prior application, Serial No. 703,004, the angle iron extends into the tubular member of the corner post and rests upon a stationary support disposed therein. In my present and improved construction the side rail 2i which is in the form ofan angle iron, extends into the tubular member of the corner post and carries its own support. This support is preferably in the form of a sheet metal plate having two portions 25 and 26 bent at right angles to each other. The portion 25 is longer than the portion 26 and is riveted to the inner surface of one of the flanges 27 0f the angle iron side rail while the shorter portion 26, is disposed parallel with and opposite to the other flange 28' of the angle iron as is shown particularly in Fig. 3. The portion 25 is secured to the flange 27 by rivets 29 while the portion 26, and the flange 28 of the angle iron are provided with perforations 30 in alinement with each, other. The top and bottom walls 12 and 13 of the tubular anember 10 are also provided with perforations 31 so that when the angle iron and its supporting member are projected into the end of the tubular member, the openings may come into alinement with each other and '1 pin 32 may be inserted to lock the parts together. One special feature of my invention involves the utilizing of the rivets 29 as stops so that when the angle iron is forced endwise into the tubular member one of the rivets may abut against the end of a side wall of the tubular member and limit the inward movement of the angle perforations 81 but they will be substan tially in alinement. The tapered pin 32 may be dropped into place but upon driving it home the angle iron will be forced back-- wardly a very slight'distance from the po- ,30

sition shown in dotted lines in Fig. 1 to the position shown in solid lines. Thus one of the rivets 29 serves as a stop to insure the substantial alinement of the openings but moves back upon the driving of the pin into position, so as to not interfere with the proper locking artion of the latter. The two perforations 30 are of substantially the same size and the wall 26 of the supporting member is of such a length that its outer and terminates substantially flush with the end of the tubular member 10 when the parts are in proper position. Thus the angle iron may be inserted with the flange'28 as a top wall as shown in Figs. 1 and 3 or it may be turned over and have 'its ends reversed so that'the flange 28 is at the bottom and may serve as a support for a series of bed slats in case it is desired to use such in place of the ordinary metal spring frame.

Although when the bedstead is set up 1 preferably employ a side wall formed of an angle iron and a supporting member as shown in Fig. 3, yet when the bed is onexhibititon or being shipped, I provide a special form of connecting member as shown in Fig. 6. This connecting member involves a piece of channel iron 33, having its opposite flanges provided with perforations 3%, the size of the channel being such that it will fit into the tubular member. The head and foot of the bed may be brought together as indicated in Fig. 7 with the chan n el connecting them and holding them r1g1d in respect to each other. This form of channel iron is inexpensive to manufacture and is very eliective in holding the parts in proper elative positions. The same pins 32 are used in securing this channel in posi tion as are used in connection with the side rails so that the pins are always in use and the liability of losing said pins is thus very much reduced if not eliminated.

)ne of the most important features of my invention involves the plate 35 shown par ticularly in Fig. 4. This plate is substantially rectangular in form and is curved,

bent or flat depending upon and conforming I to the shape of the post; The plate has two such size and slots 30 therein which are oi so positioned as to receive the extension 1618 of the tubular member and to liem alinement with the slots in the post, which receive saidextensions. This plate performs several impcrtant functions. It is preferably of steel, whereas the post itself is often of softer bramror is brass coated or enameled. The vertical end of the side walls 14 and 15 of the tubular member come in direct contact 10 with'the outensurface of the plate 35 and are prevented*from marring the post or indentingmr cutting into the latter due to relative movement of the parts in the movement of the bedstead. It distributes the 5 pressin'eever such a large area of the post that ther'ezislittle if any marring of the latter and the corner post fastening may be removed: from :the post leaving t e latter free from disfigurement. A further imporgotant advantage of this plate is that it increases the range otthe wedge 18, without exposing the openings 17 It is evident that the wedge 18 in; being driven into place draws the extensions 16 into the post and in doing: sex-the. free edges of the sides of the wedge approach the end of the opening 17 toward the body of the tubular member.

If theseopenings 17 be made of such size that they will'be drawn into the slots in the so sides of the post then there is the possibility that the wedgemay come into engagement with the said end of the opening 17 and further downward movement of the Wed e Will have no effect in binding the parts. If t 1e openings 17 me made of such size that there is no possibility of their being drawn into the slots in the post then they may be exposed and render the device unsightly as well as providing apertures through which vermin 40 may gain access to the interior of the post. The plate 35 permits the wall of the post'to be comparatively thin, insures the concealing of the apertures 17 and avoids the possibility of the wedges'binding against the ends of the apertures toward the body of the- 'tubular member. As indicated in Fig. 1 of the drawings the edges of the wedge are till a considerable-distance from the end of the apertures 17, but at the same time to said apertures come within the slots 36 of the plate 35 and are concealed and protected. It is of course evident that I may employ this plate 35 as well as the wedge 18 and the connecting channel 33 in' the specific construction oftubular member illustrated in the prior Patent No. 1,048,256. It is also evident thatI may employ all of the features above described and hereinafter claimed, in one device or that certain of the features may be omitted without materially detracting from the efficiency of the others. Most of the features constituting the sub ject matter of the present application were disclosed in my prior application 770,095
